Imam Rassi’s Mu’tazili/Zaydi Theories described in English

Thanks to one of our readers, it has come to our attention that an academic named Abrahamov has made a detailed study (originally in Hebrew, now also in English) of Imam Rassi’s Mu’tazili study of the Holy Qur’an, and his position on the subject of Imamate, which is the Zaydi position.
These are available online, at the following links, and provide an excellent insight into Imam Rassi’s thinking, as well as the views of his contemporary opponents:
1. Regarding the Interpretation of the Qur’an in the Theology of al Qasim bin Ibrahim (an excellent summary of Mu’tazili Qur’anic interpretation)

2. Regarding Al Kasim bin Ibrahim’s Theory of the Imamate, which includes his theories on:
(a) the obligation to appoint an Imam
(b) the signs attesting to the legitimate Imam
(c) A refutation of the Rafidite (i.e. 12 Imamer) doctrines concerning the Imamate

When we refer to “Imam Rassi” we mean Imam al-Qāsim bin Ibrāhīm bin Isma„īl bin Ibrāhīm bin al-Hasan al-Muthanna bin al-Hasan bin Fātima bint Muhammad, the Chosen Prophet, peace and blessings be upon him and his progeny. Al Qasim bin Ibrahim was born in 169/785 and was based in a place called Rass, near Medina. Translations of some of his other works are available at the imam rassi society scribd page and the zaydiyyah.wordpress blog.
